Universität zu Köln All this is a real struggle… Extra commitment for PV only: > 100 Mia Euro (10↑11) Wind + PV- current costs more than 25 Mia Euro (2013) representing a market value of less 2,5 Mia Euro - but „Energiewende“ is mostly for electrical power - no solutions for car fuel (well, we have Russian gas) - Politicians have changed technical issues to emotions…

9
Universität zu Köln All this is a real struggle… The EMOTIONAL campaigns - everybody claims to save the planet -„green current“ is a priori good (many commercials) - small individual power plants are better ( not true) - green flying, mailing, driving is in (many commercials) - even power companies sing the RE song (many commercials) - everybody badly wants to earn money with RE - BUT everybody cries: NIMBY ! to power lines and turbines

14
Universität zu Köln All this is a real struggle… The TIME mismatch HUGE intermittend and unreliable RE production No storage Second line of conventional power plants needed (suffering) Give away of overproduction to neighbors (complaining) Growing cut-off of excess RE current (even more expensive)

18
Universität zu Köln All this is a real struggle… The SPACE mismatch Large RE power production in North Germany Certain closing of Nuclear Plants in South Germany New HV trunk lines are needed - big NIMBY ! Send overproduction to neighbors (complaining) Growing cut-off of excess RE current (even more expensive) Dream of the European Copper Plate

21
Universität zu Köln All this is a real struggle… The E - MARKET dilemma Guaranteed acceptance of all RE power (independent of demand) Rolling out known technology – very little R&D incentive Dream of the European Copper Plate (enables European market) Send overproduction to neighbours (complaining) Buy underproduction from neighbours Store overproduction at neighbours Cut-off of excess RE current (expensive) The painful market distortion: a sick (non-) merit order

22
Europäische Strombörse EEX : One price for all First all RE are accepted at ZERO incremental cost („Fuel cost“) The remaining energy is produced by the conventional plants

23
Universität zu Köln All this is a real struggle… The E - MARKET dilemma Energy is priced, price is frequently very low Customer pay independent of demand/supply situation All plants are trying to compensate for RE fluctuations Brown coal is running Gas plants are shut down completely NO FAIR MARKET MODEL KNOWN

24
Universität zu Köln All this is a real struggle… The Customers´ dilemma Cost of production has been rising Future cost of transport rising (The joy of a „natural monopoly“) Smart metering ? Many rich guys get much richer ! Owners of PV-cells need to market their energy in the future ? Electro – Car ? Battery unit in the basement ?

25
Transportation RE - Umlage Production cost a la „Merit Order“ Sundry Taxes Everyone pays the Umlage, but it represents only < 20% of energy produced

26
Universität zu Köln All this is a real struggle… The MAIN MISTAKES Unlimited wind- and PV- installation volume Unlimited priority feeding into the grid – killing the market concept Supporting essentially only known technology A powerful RE industrial lobby has been established Political fear of accepting mistakes and exaggerations Better: Back to the R&D – labs ! Back to pragmatism – less political hot air !
